#3. HoverCards

Hovercards get rid of unnecessary opening of tabs. Whenever you want to check out something like a YouTube video, Imgur image, Tweet, Reddit or an Instagram post, you can just hove the mouse pointer over the link.

Guess what? It will display the content of the webpage, to which the link points. In case you are interested, you can use Click For More option.

The best thing about this is you can even play a YouTube video inside the card. And, this one can reduce the browser tab clutter.
